PRINCIPLE OF OPERATION
Images may not reflect actual tool
When the tool is connected to a powerunit, operation is controlled by an actuator. When the actuator is depressed, oil is sent to the
front side of the piston forcing it and the nose assembly collet rearward. This action causes the jaws to clamp on the fastener pintail
and pull the material together. Further force breaks the pintail off. When the actuator is released the piston returns forward. The spent
pintail is evacuated out the back of the nose assembly by the vacuum system.
